About Taurodeoxycholic acid (TDCA, an ox bile constituent)
Taurodeoxycholic acid is a bile acid naturally present in ox bile extract, included in some fat-digestion/gallbladder supplements. It is chemically distinct from tauroursodeoxycholic acid (TUDCA), which has its own separate research base — the two must not be conflated. No human RCTs support a standalone dose or benefit for taurodeoxycholic acid itself; some research has linked it to promotion of colonic cell damage at high exposure, so it is not a compound to overweight.
